The invention discloses an underwater glider closed-loop active flow control device based on steady blowing and sucking flow and relates to the field of active flow control. The device comprises a diffused silicon pressure sensor arranged at the front end of the bottom of an underwater glider wing, wherein the diffusion silicon pressure sensor is connected with a control unit, the control unit isconnected with a micro water suction pump set located at the front end of the bottom of an underwater glider wing and a micro water spraying pump set located at the rear end of the bottom of the underwater glider wing, and the micro water suction pump set and the micro water spraying pump set are connected with a water storage bin through pipelines. The front end and the rear end of the upper surface of the underwater glider wing are each provided with a plurality of mechanical nozzles, the micro water suction pump set is connected with the mechanical nozzles located at the front end of the upper surface of the underwater glider wing, and the micro water spray pump set is connected with the mechanical nozzles located at the rear end of the upper surface of the underwater glider wing. Localor global effective flow change is obtained through local disturbance, and then the purposes of increasing lift, reducing resistance, improving a flow field, restraining noise and the like are achieved.
